【推荐1】The development of artificial intelligence (AI，人工智能)is a hot topic these days. AI makes it possible for machines to learn from experience and perform human-like tasks. But what is the future of AI? Will it be a good thing? We asked students what they think.

【推荐3】We can text WhatsApp, Facebook message and Snapchat — but are we losing the convenience of the phone conversation? Who has time to chat when you can spend hours on WhatsApp?

Most of my phone calls are less than a minute long. If I unintentionally hit answer instead of pressing ignore button, I usually say, “Hold on, I’ll call you back,” before quickly typing out a “whatsup?” text. My list of recent phone calls is limited to four people and unless we live together, are related, or dating, there’s very little chance that you’ll be added to that list.

It seems I’m not the only who’s abandoning the phone call. The average adult spends more time on media or communication per day than on sleeping, but among all that communication, the phone call is the medium that’s falling.

So why has the phone call fallen out of favour? Many messaging apps seem to have created a grade of communication, so that the phone call is no longer the standard way of conversing long distance, but a relatively intimate thing.

Rachel, 24, says that she used to speak to all her girlfriends on the phone but now only calls a few. “I rarely even speak to good friends on the phone and if they call me I’m like, ‘Hello, is something wrong?’,” says Rachel. “If I do a phone call it feels really official, like it’s a big deal.”

Instead of taking the time to ring a friend and catch up, it now seems easier to send a short message. And unless you’re very close to someone, an unscheduled phone call can feel like an intrusion. While text messages can be put to one side for hours or even days, a phone call demands attention in the moment.

But while text messages and emails may be a more efficient way of sharing basic facts and information, they’re not necessarily the best way of communication. We may be communicating more than ever before, but we seem to be listening far less.

There are people who still insist that sharks never attack human beings unless they are bleeding or wounded, but this thought has not been clearly proved. In the past few years, on both the Atlantic and Pacific coasts, there have been cases of shark attacks which resulted in death. And just how many of the swimmers who have disappeared were victims of shark attacks will never be known. Clearly, these violent fish can be dangerous. Several species are known to attack human beings, and it is believed by some experts that certain sharks, once having tasted human blood, develop a taste for it.

The chances that one will come across a shark are small, but certain measures should be taken by everyone. Putting hands or legs over the side of a boat in warm water is to be avoided. Swimming far out from beaches is inviting trouble. No swimmer should go great distances from shore alone, or go into the water when nobody else is about. Skin divers, particularly those who go deep down in the water or among rocks and ledges(暗礁) that serve as hiding places for sharks, are taking unnecessary risks.

If one is in a boat that is rubbed against by a shark, he should remember the creature is not trying to upset his boat; it is probably trying to rub off sea lice (海虱). A beat, especially on the nose, will scare it away. If a swimmer comes across a shark, he should swim away as quietly as possible, trying to avoid making it angry. He should also head for shore (岸) as quickly as possible.

On March 30, Shanghai vice-mayor Wu Qing made the first 5G video call on a Huawei Mate X Smartphone. Shanghai has also become the first city in China to start testing 5G networks.

About 100 times faster than 4G networks, 5G will let people download and upload data(数据)     faster than ever before. But 5G won't just bring faster mobile internet. People can use it for many other things as well.

For example, 5G will help to make self-driving cars safer. Today's self-driving test cars have one problem-lag(延迟) . When the car "sees" an obstacle(障碍物) , it sends this information to a data center and receives instructions, However, it will be some time before it sends and receives this information. With this kind of lag, the cars might crash because they don't receive instructions in time. With 5G, this lag will be greatly lowered, making the cars safer.

5G could also be used to power the internet of things (IoT) , that is, a large online network that connects all things and people. Fast internet speeds will be the key to developing this technology.

The IoT could be used in a lot of ways. For example, with IoT, your refrigerator could automatically (自动地)   place an order online for eggs when it finds that there are no eggs left inside.
